Input for vector to scalar volume from jpg not working

I am sorry if this question was already posted.

I am trying to reconstruct a 3D model from an MRI series of jpg images, I am following the tutorial for the import of png images, so first after importing I set the image spacing and origin in the “volumes” module. Then when I try to input the vector volume in the “vector to scalar conveter” module, I cannot select the previously imported volume.

Am I doing something wrong?

Maybe it is already a single-component (grayscale) volume. Can you check what value do you see in Volumes module / Volume information / Number of scalars? If you see 1 there then “Volume type” should be “Scalar” and you don’t need “Vector to scalar converter”. If you see 3 or 4 then you should see that “Volume type” is “Vector” and so the volume shows up in need “Vector to scalar converter” module’s input selector.

Hi Andras, thank you for your reply, it was indeed already a greyscale volume!
